To all whom it may concern,.-

Be it known that I, TozAURo SUZUKI, a subject of the Emperor of Japan, residing at N o. 401 Jiheishinden, Sulla-Mura, county ot Minami Katusushika, prefecture of Tokyo, Japan, have invented l,certain new and useful Improvements in Drying Apparatus, ofvwhichv the following is a specication.

My present invention relates to drying-,ap-

o means for desiccating -the material by a drying gas, such as ot/air, passing through the layers V,ti/material treated. l

The principal objects of my lnvention are= to provide apparatus adapted to thoroughly and uniformly dry the material in as short a period of time as possible, without materia-ll)T aHect-ing the quality,color',` luster, or

.other characteristics of the material which Y it is desired to preserve.

`Other objects o-f'my invention areto facilitate the operation of myimention by disposition and coaction of parts, and to pre- 'vent Ygases from vpassing through or coming intov contact with materials being treated, after the gases have become dlfusedv with moisture in the desiccating of the material.

the conveyance.

In the drawing, forming a part of this specification: Figure l is a transverse sec*- tional ViewI through what is hereinafter termed a conveyance for' the materials treated?? Fig. 2 is a View partly in side eleration and partly in longitudinal section of Fig. 3 Ais a sectional plan View through the conveyance. Fig. 4 is a sectional view throughthe conveyance and its enveloping casing,and showing air being delivered to the conveyance Ain a predetermined direction. Fig.'5 is a view similar to Fig. 4 indicating the air traveling in a direction counter to that shown in. said iigure. A

Similar characters refer to similar parts throughout the views.

A conveyance 1 is ity of floors 2 which extendbetween oppoand'l and between Walls 7 and sui-table doors 7 at right angles tothe said walls l and 1". The said floors 2 dividethc'conveyance into a plurality of compartments 9, access to whichis gained through doors 7, and within each compartment I provide ledges 5, disposed slightly above the said oors 2, adapted to re'ceive trays 6 of openwork material for containing ,shown in Figs. 2 and 3 of that a set of doors ,7 may 'bedisposed at each endv of the conveyance and in this way provided with a plural-l the materials to be treated. l prefer to; mount the said conveyance lupon wheels 8,.

to facilitate transportation, a'nd also,l to provide two tiers of compartments .9, as clearly the drawing, so

compact conveyance havinga maximum' ca.

l n pacity for materlals to. be treated, consistent with its magnitude is provided.

The walls 1 are provided with a plurality of ports 3, one for each compartment 9, disposed subjacent tothe floors 2, while the opposite wall l is provided with a plurality of ports et subjacent to the floors 2, and below the said ledges 5 of, the compartments. By this disposition of ports, va current of air may traverse the compartment, for instance, entering port 3, pass through the trays 6 and layers of materials thereon, and find egress througlrport 4, or vice-versa.l

Means for conveying, controlling and directing the gaseous currents for drying purposes, is disclosed in Figs. 4 and 5 of the drawing, in connection. with the :beforemenL tioned conveyance. This means includesa casing A enveloping the conveyance 1; "conduits D for the gaseous fluids; and exhaust ducts F communica-ting with the chamber containing the conveyance 1 through ports E. f

The relative Siae of the conveyance'l to its receiving chamber formed by casing is such as to provide passages B and B at the sides adjacent the walls 1 and 1-of the conveyance, and within-said casing defiecting Iplates d are provided and so disposed that one'margin of'each plate will he4 alinedwith the upper margin of one'of the ports 3 and 4. These plates (l extend vdownwardly toward the adjacent walls of thc casing A. and catch subjacent plate is reduced in size in the order from top to bottom, for

a purpose to be subsequently described.

In order to provide for theA economical `consinnption ot the desiccating qualities of the'gas, conduits D open into distributing ducts D', ports C of which open closely adjacent to the lowermost compartment of the conveyance l, vand .these ports C are so disposed `below the deflectin'g plates CZ that the gas rising from the distributing ducts- E is caught by saidv plates and uniformly distributed into the 'chambers9.` As shown in the drawings,

adjacent and a valve G is 'adapted jtogcon# the ports C and E are closely,

trol either oit said atfljaeent handle .l may 'h d it Clesirahle to eo G 'Whit-ll controls eonnnnniea" Y or E with the passages l and B", to operate in nniaon. that is, to ope 'at'.iif'evli),7 eonneetthe valve (l. that when the port (lis open to pasa-ange l, aa shown in Fig'. el, then the port l at the opposite side ot the com/e3.L ance l is open to the. paaage B. or riet reraa. are diaeioaed in 5 of the drawing.

rlihe operation of the device .is as follows: The trays eontaining; the material. to be treated are plat-ed within 'the Compartment El, aereas thereto being' rained through doors; 7K The eouvevanee is then wheeled or otherwise transported into easing A with the .lleleetine` plate. (l registering-as described. (laaeoua fluidr` as tor instance hot air, adapt ed to desieeate the materials on the trays7 is admitted into one of the passages formed adjacent the conveyance. For inst-ance, in Fig. l o'tvthe drawing, `gaseous fluid intls ingress tlnfoue'h port B to passage B; is unit'olinl;Y distributed hy platos d through ports il: traverses through chamber 3, passing throujfrh the layers of materials on the tr*t ys, lindseeress tl'ierefroni through port 4, and is, eoudueted down passage.

When die valveb (lr are actuated to the position shown in Fig. 5 ot the d anfing, then the current travels in a counter direction as previously deaerihed, I and the materiele treated beeonie unifornil)y dried.

It is to he noted that the gaseoua ,:urrenta do not alriin over the materiale7 but pase, through layers formed by th Seine; that after havingl onee pasaed through one ot the chambers the moisture ladened llnid 'hurle etre-e without propagating; al'iout. the nella rial treatrnh but iS conducted array and. that-ln' means of the eonveyzun'fe l. and reeeiving ehaniber A the former may' he disposed to receive the currents ot deaieeat ing;I gaa-ea and utilize the .'naxiniuni drying okualitief` thereof. in its passage through the aptmratufs.
